The gram-scale isolation of the major flavonolignan diastereoisomers from milk thistle ( Silybum marianum) extract provided an entree into the isolation of two related analogues that are present in extremely minute quantities. The isolation and structure elucidation of these two new compounds, which we have termed isosilybin C and isosilybin D due to their structural similarities to isosilybin ...
Background and objectives: Silymarin is a unique flavonoid complex with documented hepatoprotective properties. Silybum marianum hairy root culture as a source for producing silymarin has been an important strategy for study the cell signaling pathway. In the present investigation Trichoderma strains- Silybum marianum hairy root cultures interactions have been studie...
Effect of flavonolignans derived from silybin on mitochondrial production of reactive oxygen species
Silybin, a secondary metabolite isolated from the seeds of the blessed milk thistle (Silybum marianum) was discovered as the first member of a new family of natural compounds called flavonolignans in 1959. Over the years it has received the research attention of many organic chemists. This research has resulted in a number of semisynthetic derivatives prepared in an effort to modulate and bette...
Flavonolignans from milk thistle (Silybum marianum) have been investigated for their cellular modulatory properties, including cancer chemoprevention and hepatoprotection, as an extract (silymarin), as partially purified mixtures (silibinin and isosilibinin), and as pure compounds (a series of seven isomers). One challenge with the use of these compounds in vivo is their relatively short half-l...
Milk thistle (Silybum marianum (L.) Gaertn.) is one of the valuable medicinal plants which used in the treatment of liver disorders. The major active constituents in this plant are flavonolignans, collectively known as silymarin which is a mixture of three isomer silybin, silydianin and silycristin. Its therapeutic properties are due to the presence of silymarin. The seeds contain the highest a...
